I think we cleared what we could at Commit https://github.com/weidai11/cryptopp/commit/1d0df34ae830. The limitation is, I could only find OIDs for some of PKCS #1 and SHA3-256, SHA3-384 and SHA3-512. We might be missing some support. At the moment I am not sure what needs to be done for https://github.com/weidai11/cryptopp/blob/master/pkcspad.cpp#L56. ... template<> const byte EMSA2HashId<SHA256>::id = 0x34; template<> const byte EMSA2HashId<SHA384>::id = 0x36; template<> const byte EMSA2HashId<SHA512>::id = 0x35; I checked Botan and I did not see support for SHA3 in its OID registry. Jack is usually very good about these sorts of things, so I'm guessing there's nothing in the standards right now. If you can dig up the additional OIDs, then we would be happy to add them. Someone on the IETF's SAAG list may be able to help. Also see https://www.ietf.org/mailman/listinfo/saag.
